I'm trying to extend the height of my 20 year old Heatilator chimney. It's a solid pack insulation 8" ID chimney (IC8 series part numbers.) Heatilator no longer makes this, and none of the distributors in their database have any old stock. Does anyone have any ideas of how I can proceed? I'm looking for someone who might have a part (I need 36", IC836 or equivalent pieces), or whether there's an alternate chimney I could use to replace the whole thing. I'd prefer not to replace the fireplace, which is a Heatilator FP36 (woodburning) from 1985.

Thanks, I'm not near Madison, but am willing to pay for shipping if your guy has the right pipe. It's actually not a triple wall. It's a solid pack, 8" ID and about 10.5" OD. The Heatilator part number I'm looking for is IC836, though I could also use smaller pieces to make up the 36" length, such as two IC818's. Does it make sense for me to contact your installer directly? If so, please give me his contact info.

Chimney sections

I have 2 36" sections of the solid pack insulated chimney for the FP36. I used to have 3 and recently sold one and although I still have the actual firebox also I'd be willing to junk that and just sell the chimney sections together or separately. Thanks

You will probably endup buying new pipe any pipe of that same style should work if you get the new pipe in the same inside diameter but you will have to run all new from fireplace out cause most brands do not inter change or if there is a brand name on the pipe you could get the same brand and put it on the old pipe. A company had to make that pipe for hetalator you just have to find which one.

NCL, that factory chimney was mfd. tested and listed by Heatilator. You cannot mix other brands or models of pipe including other HL chimney. You should not be re-using old used chimney. If the old chimney is unused in the original packaging, that's fine.

The only chimney pipe that meets the original pipe is the pipe tested and listed by the mfr.--period. Fireplace chimney is not like woodstoves, heater chimney or B-vent where you can use whatever brand you want. The air cooled chimney is extensively tested with that fireplace. If you took another brand chimney and somehow modified it to mate up with that fireplace and it was not tested with it, you could burn the house down but at the very least you void the warranty and listing.

Keep in mind there are a few fireplaces out there tested and listed with other very specific chimney pipe. For instance, Some of the early Heat N Glo Energy Master fireplaces were tested and listed for use with certain Temco and Majestic air cooled chimney. They made a special adapter for each. This was because at the time, HG did not roll their own chimney pipe. Nowadays, their pipe is made by their sister company Heatilator.

If you cannot find the same chimney as original, check with the mfr.'s technical services for any possible listed substitutes.

I have the pipes you need

tasuer, if you still need these chimney pipes, I have three available...IC836. I purchased a used insert and pipes and didn't need all the pipes, so I have these available. Let me know if you need them. I'm located in Minneapolis, MN.
